In reply to Mick Ward:
An overhanging short corner I seem to recall and quite strenuous at that. It was Anthropology when I did it in the late 60's, but the original name now used. I think Joe Brown & Nat Allen thought it was new, but there was so little feedback in those days.
Just checked Roscoe's Llanberis North and it was Anthropology, but with the note that Rift Wall done in 1949 '...covered much of the same ground'.
